19 Claims. (o1. its-gm This invention relates to trucks and, more particularly, to railway car trucks'having roller bearings with provision for allowing angling of the journalbox containing said bearings with re spect to the supporting frame. 7

The principal object of my invention,- generally considered, is the provision of a car truck having side frames between the upper and'lower end extensions of which are positioned journal boxes which are preferably of the roller bearing type, said journal boxes being connected to said side frame extensions and so formed that the desired amount of angling with respect thereto as well as vertical movement therebetween is permitted whereby the tendency to unevenly load the axles and roller bearings is obviated.

An object of my invention is the provision of a car truck, the side frames of which have upper and lower end extensions with journal boxes positioned between said extensions and pedestal means positioned on either side of each journal box and spacing said extensions to allowclearance between the same and the box, through bolts being preferably provided joining the exe tensions and pedestal means, said box being formed with flanges or guides embracing or cooperating with said pedestal means, suffi cient clearance, however, being provided to allow 'relaa tive motion of the box with respect thereto.

Another object of my invention is the pro vision of a car truck, preferably having'roller bearing journal boxes connected at the ends of the side frames thereof betweenpedestal means, said means; being sufficiently long to'space the upper and lower side frame members a sufficient distance for providing thedesired amountof clearance between the bottom of the journal box and the corresponding tie member to provide a flexible connection between said boxand frame,

A further object of my invention is the provision in a truck of the class under consideration Other objects and advantages of the invention relating to the particular arrangement and combination of the various parts will become ap-' parent as the description proceeds.

Referring to the drawings illustrating my in- 30 vention, the scope whereof is defined by the appended claims:

Figure 1 is a side elevation of'a portion of a railway car truck shown partly in longitudinal I vertical section centrally of one of the side frames 7 05 thereof. I

,Figure 2 is a transverse vertical section on the line 2--2 of Figure 1 looking in the direction of the arrows. v I

Figure 3 is a fragmentary horizontal sectional view on the line 3-3 of Figure 1 looking in'the direction of the arrows. V 1 Figure 4 is a fragmentary sectional view corresponding substantially to Figure 3 but showing a modification of my invention.

Referringto the drawings in detail, like parts being designated by like reference characters and first considering theembodiment of my invention illustrated in-Figures 1,2 and 3, one end of a car side'frame is illustrated although I do not wish to be limited to such a showing as the principles of my invention-may be embodied in other forms of trucks'than here illustrated. Al-' through a side frame lof the arch bartype havingfa compression member 2 a tension inem- 35 her 3 and a tie member 4 is illustrated,- I do not i wish to be restricted to such a showing as my invention may be embodied in aside frameofotlier construction than that shown. The substantially horizontal overlapping end extensions 5 and 6 of the'compression and tensi'on'members 2 and 3 of the sideframe arepreferably spaced from the corresponding extension '7 of the tie member 4 by means of a plurality of pedestal members or means 8 and 9 respectively, forming. jaws depending from the side frame adjacent the ends, said pedestal means being sufficiently long and spaced apart a sufficient distance and preferably notched to accommodate the journal box 10 therebetween while allowing clearance l1 between the bottom of said journal box and the top of the tie member extension 7 for allowing verticalj'movement and angling of said journal box with respect to the frame. These pedestal pieces 8 and 9' are preferably provided with slots 12 therein receiving through connecting bolts 13 preferably extending vertically, when in normal position,as shown, and provided with heads 14 prevented from turning by rotation preventing means-l5 ,whilefithe nuts 16 are being tightened thereon, lock washers 17' being advantageously used as indicated. The pedestal means 8 and 9 are preferably bifurcated at'their ends to form flange portionsIBextendingaround the adjacent frame member for holdingthe pedestal means square with respect thereto. The inner and if desired both pedestal means may advan- -tageously be formed with strengthening means such as the rib or flange portion 19, shown most clearly in Figure 3.

The journal box 10 is preferably positioned between the end extensions'of the side frame and the pedestal means or side frame jaws 8 and *9, as shown, the upper surface or roof of said box being preferably crowned orcurved longitudinally of the box and straight transversely thereof as indicated at 20 to engage a dissimilar or flat surface on the adjacent portion of the frame 1 to allow angling between said box and frame in an" upright or vertical plane while holding the same against axial rotation. .Thesides of thejournal box adjacent' the pedestalmeans 8 and 9 are preferably formed -withguiding portions or flanges 21 ,extending on either sideof the adjacent portions of the pedestal means 8 and 9 with suflicient clearance for allowing a slight amount of angling in ,a horizontal plane. A

- greater amount of angling in sucha plane is satisfactorily provided for, as shown in" the modification illustrated in Figure 4 in which modification the pedestalrneans 9, as well as the correspondingpedestal means on the opposite side of the journal box, is. crowned or curved horizontally whilepreferably extending vertically as shown,

. or lip portions 21* thereon.

where it engages the guiding portion of the journal box l ot'said guiding portion being preferably formed of a corresponding curvature with sufficient clearance between the same and the flange -Except for this change to provide complementary are shaped surfaces on the box and frame to facilitate lateral angling, which surfaces are also spaced apart to provide for limited bodily lateral movement therebetween, the second modification may be the samev as illustrated in Figures 1,2 and 3, it being understood that the pedestal pieces of either modification may be alternatively formed with or ,without strengthening flanges or ribs '19. jl?ositioned within the journal box in accordance with usualpractice with roller bearin journal boxes is a bushing or roller bearing raceway. 22 and imivardly spaced from said bushing 22 is another bushing 23 surrounding the journal 24 and between said bushings are roller means 25' which may be of standard construction. The details shown for holding the bushing 23 on the journal may beof standard construction not necessitating further description and the usual form of grease grooves 26 may be provided, if desired. The journal box is preferably closed at its outer end by means'of a cover or lid 27'preferably connected theretoby means of cap bolts 28 preferably formedwith any desired type of locking means 29.

Agasket 30 of the usualcharacter may be pro place as shown particularly in Figure 2 by means of a screw or other connecting means 3'7.

It will be apparent that by virtue of the aforedescribed construction, a connection between a journal which is preferably of the roller bearing type and an associated side frame is provided allowing a limited amount of vertical movement therebetween and angling in all directions thereby obviating the tendency to unevenly load the axle and roller bearing when the truck is rounding a curve. Such flexibility is more necessary in a roller bearingbox than with the usual design in which'a brass is applied to the top of the axle because the axle in this case is completely surrounded by .the bearing and housing and it is connection between-the frame, pedestals and. journal boxes isfacilitated and the connecting nutsare morereadily applied and kept tight.
